Search engines such Yahoo and Google among others has played significant role Web data access. However these search engines has limitations. These search engines are based on a keyword search which lacks semantics in the retrieval process. To cope with the Limitations of current search engines, Semantic Web was introduced. Semantic Web enables retrieval of data on the Web semantically. In semantic Web, data is standardised in a format that enables retrieval of such data semantically. But Semantic Web also has challenges where retrieval requires complex structured query such as SPARQL which is not simple are using Google like natural language query. This paper presents an approach of automatic semantic query formulation that enables retrieval of semantically structured data using natural language. The proposed approach is based on using machine learning and the result has shown improvement of 17.4% compared to existing approach in FREyA in terms of effectiveness formulated natural language queries to structured query. © 2005 – ongoing JATIT & LLS.

The magnetic storm of 9 March 2012 is a single step intense storm (Dst = -143 nT) whose main phase begins around 0100 UT and lasted for almost 11 h. The increases in NmF2 recorded 33% and 67% incidence respectively during the main and the recovery phase of the storm at the stations considered. The increase in hmF2 occurred concurrently with the increase in thickness parameter B0 between 0000 and 1100 UT, and a simultaneous decrease in the shape parameter B1 for the entire mid-latitude stations. Generally, B1 responded to the storm with a decrease away from the quiet day average, and decreased simultaneously with the increase in NmF2. B0 displays higher variability magnitude during daytime than the nighttime period. The occasional differences in the response of the ionospheric parameters to the storm event are attributed to longitudinal differences. Variation in hmF2 and NmF2 is projected to change in B1, but the rationale behind this effect on B1 is still not known and therefore left open. The two IRI options over-estimate the observed values with that of URSI higher than CCIR. The over-estimation was higher during the nighttime than the daytime for NmF2 response for the mid-latitude stations and the reverse for the equatorial station. A fairer fit of the model with the observed for all parameters over Jicamarca suggests that equatorial regions are better represented on the model. Extensive study of B1 and B0 is recommended to arrive at a better performance of IRI. © 2013 COSPAR. Published by Elsevier Ltd. All rights reserved.

Present study was carried out during the year 2006-2007 on dried earthworm powder collected from culture of Eisenia fetida in vermicomposting units and focused on the effect of the dried earthworm on microbes determining the anti-microbial and anti-fungal properties of the worms, as well as the chemical composition of worms obtain from vermicomposting units. The earthworm powder was also subjected to analysis of nitrogen and potassium using standard procedures. Antimicrobial disc hffusion suspecting tests were carried out against Bacteria (Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) as well as the fungus Candida albicans with the following treatments: Control, earthworm powder in water (1:1), earthworm powder in water (1:2) and earthworm powder in acetone (1:2). The technique involves using disk diffusion susceptibility testing where disks from both the pure and &luted honey as well as the antibiotic disk erythromycin (control) were impregnated onto the surface of the Mueller Hinton agar. The study conclusively proved that the earthworm powder (all hlutions) has antifungal properties which would be effective in treating fungal infections, such as candidosis whereas did not indicate the anti-microbial properties which may be attributed to hfferent composition of elements in earthworm powder obtained from vermicomposting unit rather than garden soil. ANOVA analysis (Single factor) at p = 0.05, proved that differences between the different concentrations of earthworm powder treatment containing colonies of C. albicans was significant, inhcating the effect of earthworm powder by inhibiting the growth of the fungus C. albicans. © 2011 Academic Journals Inc.

Present investigations were carried out during the year 2006 - 2007 at University of Guyana, Georgetown focusing on recycling organic waste using vermitechnology and use of vermicompost and vermiwash obtained from the vermitech in varied combinations for exploring the effect on soil and productivity of Okro (Abelmoschus esculentus) in Guyana. The soil quality was monitored during the experiment along with plant growth parameters of Okra. The study revealed that combination organic fertilizers vermicompost and vermiwash combination compared with control and chemical fertilizers had great influence on plant growth parameters. The average yield of Okro (A. esculentus) during trial showed a significantly greater response in comparison with the control by 64.27%. The fruits were found to have a greater percentage of fats and protein content when compared with those grown with chemical fertilizers by 23.86 and 19.86% respectively. The combination treatment vermiwash and vermicompost combination was also found to have a significant influence on the biochemical characteristics of the soil with marked improvement in soil micronutrients. The combination treatment was the found to be better suggesting qualitative improvement in the physical and chemical properties of the soil, which is substantiated by composite, index {Rank 1 for vermicompost and vermiwash combination with composite index of 9}. This biological method of crop cultivation is sustainable and improves soil health rather than conventional methods based on the earlier observations. © 2010 Academic Journals.

In this study, we add to scholarly knowledge in simple terms, the forces or energy defining certain adsorption phenomenon, using isotherm models. GCMS measurement of equilibrium phase atrazine after adsorption onto Sheanut shells (SS) acid derived activated carbon were fitted into the D-R and Temkin isotherm relationships for energy data estimation. Sorption energy value (BD), mean free energy (ED) and heat of sorption (B). They were estimated as 0.7600mol2KJ-2, 0.8111 kjmol-1 and 0.790Jmol-1 respectively. The parameter predicting the type of adsorption was evaluated BD, B < 20kJ/mol and ED<8 which is an indication that physisorption (Non specific adsorption) dominates chemisorption and ion exchange. The D-R model with a higher correlation coefficient values, R2 = 0.979 proves a better choice in explaining sorption energies. Generally, sheanut shells can be used as alternative precursors for activated carbon production via the two steps and acid treatment schemes.

This information add to database an attempt to model the adsorption of dye from dyeing wastewater in relationship to certain established energy parameters. The adsorbent is thermochemically cracked shea nut shell activated carbon, the adsorbate is textile dyestuff wastewater from Chellco textile ltd., Kaduna, Nigeria. The process is batch adsorption test while the adopted models are Rudishkevich - Dubinin and Temkin isotherms. This critical study which utilizes these more recent adsorption isotherms was found to present the mean free energy values (ED =1.036 - 1.406 kJmol-1) as a direct proportionality to the theoretical saturation capacities (qD = 2.032 - 4.169mgg-1). Sorption energy values proves to be higher for biosorbent, SS/A/15 (1.364 KJmol-1),which also gave the corresponding higher adsorption capacity (4.169 mgg-1) than the other three biosorbent in the series. A thermodynamic parameter (ΔG) was investigated to be more negative with sorbent - dye contact time, within the equilibration limit. The Close similarities of analytical results to those reported in reviewed literature, and the good degree of adsorption is an indication that using shea nut shells as a low cost biomass for generating activated carbon could be a feasible outlet in bioremediation.

Tilapias are yet to reach their full aquaculture potential because of the problem of prolific breeding which usually results in overpopulation thus leading to stunted growth. The potential use of Azadirachta indica leafs as an antifertility substance in controlling prolific breeding in Oreochromis niloticus was investigated. Crude extract of Azadirachta indicaleaves. were added to a basal diet (35% crude protein) at 0.0, 0.5. 1.0, 2.0, 4.0 and 8.0 g kg -1 diet, respectively (Dl, D2, D3, D4, D5 and D6) and fed to 180 Oreochromis niloticus (90 males and 90 females) Mean±SD weight of 29.30±2.02-31.79±3.11 g twice daily (0900-0930, 1700-1730) at 3% of their body weight for 56 days to evaluate the effects on growth and reproduction. There was variation (p<0.05) in growth parameters with fish fed 1.0 g kg -1 diet showing best Mean±SD weight gain of 19.68±3.22 g. A total of 63-89 hatchlings were counted in the control tank in the 3rd week and 35-51 hatchlings from fish fed with 0.5 g kg -1 diet in the 5th week, there was no breeding in the groups; D3, D4, D5 and D6 during the course of this study. This study infers that Azadirachta indica leafs extract could be used in controlling prolific breeding in Oreochromis niloticus for efficient and sustainable development of tilapia farming. © 2011 Knowledgia Review, Malaysia.

Every city generates tonnes of garbage that includes organic biodegradable waste like kitchen waste, fruit and vegetable market waste, which poses a serious problem of disposal. However, if handled and treated properly, this could provide useful organic manure for agricultural application. This problem can be solved by combination of effective technologies like Biodung composting and Vermitech (incorporating earthworms for the production of vermicompost). The present study was carried out during the year 2006-2007 at University of Guyana, Georgetown to recycle grass clippings, water hyacinth and cattle dung by using Eisenia fetida the locally available surface species of earthworm. The results indicated that the organic waste (grass clipping s and water hyacinth) were successfully processed through partial biodung composting and vermicomposting during the period of 60 days. The temperature study during biodung composting showed two peak rise of temperature resulting in destruction of harmful microbes. Subsequent vermicomposting resulted in production of vermicompost confirming to the excellent nutrient status recorded in earlier experiments. The temperature study during vermicomposting showed that fluctuation was restricted to +0.83. © 2011 Academic Journals Inc.

In this paper, we present the exact solution of the one-dimensional Schrödinger equation for the q-deformed quantum potentials via the Nikiforov - Uvarov method. The eigenvalues and eigenfunctions of these potentials are obtained via this method. The energy equations and the corresponding wave functions for some special cases of these potentials are briefly discussed. The PT-symmetry and Hermiticity for these potentials are also discussed. © 2013 Chinese Physical Society and IOP Publishing Ltd.
